# [−][src]Function mynewt::kernel::os::os_mbuf_off

    pub unsafe extern "C" fn os_mbuf_off(
        om: *const os_mbuf,
        off: c_int,
        out_off: *mut u16
    ) -> *mut os_mbuf

Locates the specified absolute offset within an mbuf chain. The offset can be one past than the total length of the chain, but no greater.

- `om`: The start of the mbuf chain to seek within.
- `off`: The absolute address to find.
- `out_off`: On success, this points to the relative offset within the returned mbuf.

Return: The mbuf containing the specified offset on success. NULL if the specified offset is out of bounds.

## Search Tricks

Prefix searches with a type followed by a colon (e.g., `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g., `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
